Product details
Overview
MAX4352EUK+T from Maxim Integrated is a single-channel, high-speed, rail-to-rail output operational amplifier optimized for minimum closed-loop gain of +5V/V. It delivers 80MHz -3dB bandwidth, 240V/µs slew rate, and 620µA quiescent supply current per amplifier while operating from a +2.7V to +5.25V single supply. It is used in battery-powered instrumentation and keyless entry systems requiring fast settling and low power.
For engineers reviewing the MAX4352EUK+T datasheet, MAX4352EUK+T pinout, MAX4352EUK+T application, or MAX4352EUK+T equivalent, this page provides verified electrical specifications, SOT23-5 package details, real-world use cases in portable communications and baseband signal conditioning, and validated alternative op amps with documented gain-bandwidth trade-offs.
Technical Context
The MAX4352EUK+T employs a voltage-feedback architecture with internal compensation for stable operation at closed-loop gains ≥ +5V/V. Its bipolar process enables high slew rate (240V/µs) and fast 8ns rise/fall times, supporting wideband signal amplification without phase reversal over its input common-mode range (VEE − 0.1V to VCC − 1.5V).
It features rail-to-rail output swing (within 180mV of rails into 1kΩ), low input bias current (0.8–3µA), and integrated stability optimization for capacitive loads up to 22pF-requiring external isolation resistors beyond that threshold to maintain phase margin and prevent oscillation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 80MHz - supports video, IF, and baseband signals up to ~40MHz fundamental frequency with <0.1dB gain error |
| Slew Rate | 240V/µs - enables clean 2Vpp step response in ≤8ns, critical for pulse amplification and ADC buffering |
| Supply Current | 620µA per amplifier - allows dual-op-amp designs to stay under 1.3mA total, ideal for coin-cell or Li-ion portable systems |
| Input Offset Voltage | 0.4–12mV - ensures DC accuracy in precision gain stages without trimming in most sensor interface applications |
| Output Swing | Within 180mV of rails (VCC/VEE) into 1kΩ - maximizes dynamic range in 3.3V or 5V single-supply systems |
| Common-Mode Rejection | 60–100dB - suppresses noise coupling from shared supply rails in mixed-signal PCB layouts |
| THD @ 1MHz | −68dB - maintains signal fidelity in audio and RF front-end applications where harmonic distortion impacts SNR |
Pinout & Package
The MAX4352EUK+T is housed in a 5-pin SOT23-5 package (JEDEC MO-178), measuring 2.9mm × 1.6mm × 1.1mm, with gull-wing leads and moisture sensitivity level 1 (MSL1). Pin 1 is marked by a dot; device orientation follows standard SOT23 top-view convention.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - rail-to-rail capable, drives 1kΩ load to within 180mV of VCC or VEE |
| 2 | VEE | Negative supply terminal - tied to ground in single-supply configurations; must be decoupled with 0.1µF capacitor |
| 3 | IN+ | Noninverting input - accepts common-mode voltages from VEE − 0.1V to VCC − 1.5V; high-impedance (30MΩ) |
| 4 | IN− | Inverting input - matched to IN+ for offset voltage tracking; used with feedback network to set closed-loop gain ≥ +5V/V |
| 5 | VCC | Positive supply terminal - operates from +2.7V to +5.25V; bypassing to VEE with 0.1µF ceramic capacitor is mandatory |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4452EUK+T | Unity-gain stable; 200MHz BW, 95V/µs SR, same 620µA IQ and SOT23-5 package | Used where gain = 1 is required (e.g., voltage follower, ADC buffer); not suitable for gain-of-5+ without external compensation | Select MAX4452EUK+T only when unity-gain configuration is needed; MAX4352EUK+T is preferred for fixed +5V/V or higher closed-loop gains. |
| LMH6612MMX/NOPB | Single 5V op amp; 180MHz BW, 190V/µs SR, 2.3mA IQ, SO-8 package | Higher power, higher speed, larger footprint; requires layout redesign and thermal management | Choose LMH6612MMX/NOPB only when >100MHz bandwidth or lower THD (<−70dB) is mandatory and board space/power budget allow. |
Compared with MAX4452EUK+T and LMH6612MMX/NOPB, the MAX4352EUK+T uniquely balances 80MHz bandwidth, 240V/µs slew rate, and 620µA supply current in a miniature SOT23-5 package-making it optimal for gain-stable, battery-constrained portable signal chains where unity-gain stability is unnecessary.

FAQ
What is the minimum stable closed-loop gain for MAX4352EUK+T?
The MAX4352EUK+T is internally compensated for minimum closed-loop gain of +5V/V. It is not unity-gain stable. Attempting to use it in a gain-of-1 configuration may cause peaking or oscillation. For unity-gain applications, the MAX4452EUK+T variant is specified and recommended. The +5V/V minimum ensures stability with standard feedback networks in gain-of-5, gain-of-10, or inverting gain-of-4 topologies without external compensation components.
What is the maximum capacitive load the MAX4352EUK+T can drive without external isolation?
The MAX4352EUK+T is characterized to drive up to 22pF of capacitive load while maintaining stability and specified AC performance. Beyond 22pF, an external series isolation resistor (RISO) is required between the output and the load capacitance to restore phase margin. Figure 2 in the datasheet provides RISO values versus CLOAD; for example, 50pF requires ~18Ω RISO. Driving >100pF without RISO risks ringing, overshoot, or sustained oscillation.
Does MAX4352EUK+T support rail-to-rail input operation?
No, the MAX4352EUK+T does not support rail-to-rail input. Its input common-mode voltage range is specified from (VEE − 0.1V) to (VCC − 1.5V). At VCC = 3.3V, this means inputs must stay within 0.1V above ground to 1.8V below VCC (i.e., 0.1V to 1.5V). Inputs outside this range degrade CMRR and may cause nonlinear output behavior-but do not cause phase reversal or latch-up. For true rail-to-rail input, consider the MAX4475 or similar devices.
What is the typical power-up 1% settling time for MAX4352EUK+T?
The typical power-up 1% settling time for MAX4352EUK+T is 1µs to 100µs, depending on supply ramp rate and load conditions. Per datasheet Note 2, this parameter is guaranteed by design-not production tested-and assumes VCC ramps monotonically from 0V to final value. In practice, with a 3.3V supply rising in <10µs, the output settles to within 1% of final value in <5µs. This fast wake-up supports burst-mode operation in ultra-low-power sensor nodes.
Can MAX4352EUK+T operate from a 2.5V supply?
No, the MAX4352EUK+T has a minimum operating supply voltage of +2.7V, as specified in Absolute Maximum Ratings and DC Electrical Characteristics. Operation at 2.5V falls outside guaranteed specifications: open-loop gain, bandwidth, and output swing degrade significantly, and the device may fail to meet 80MHz bandwidth or rail-to-rail output performance. For 2.5V systems, consider the MAX4472 or ADA4891-1, which are rated down to 2.7V or lower with appropriate trade-offs.
